이 품목은 알팔파(alfalfa)를 유기용제인 아세톤, 이소프로필알콜, 에탄올, 메탄올, 헥산 및 염화메틸렌으로 추출한 다음 검화시켜서 클로로필을 제거한 후 다시 유기용제로 카로티노이드를 추출정제하여 얻어진 색소로서 주색소는 루테인(lutein)이다. 다만, 색가조정, 품질보존 등을 위하여 희석제, 안정제 및 용제 등을 첨가할 수 있다.
개요
Lutein is a dietary carotenoid that has been found in eggs and yellow-colored fruits and vegetables and has diverse biological activities. It reduces hyperglycemia-induced mitochondrial DNA damage and production of reactive oxygen species (ROS) and promotes mitochondrial biogenesis in ARPE-19 cells when used at a concentration of 10 μM. Lutein (20 mg/kg) increases nitric oxide (NO) production and decreases serum levels of endothelin-1 in a rat model of hyperhomocysteinemia. Dietary administration of lutein (0.2%) decreases monocyte migration and lesion size in an ApoE-/- and Ldlr-/- mouse models of atherosclerosis. Lutein reduces infarct size and cardiac malondialdehyde (MDA), lactate dehydrogenase (LDH), and troponin T levels, and increases cardiac levels of catalase (CAT), superoxide dismutase (SOD), heme oxygenase-1 (HO-1), and Nrf2 in a rat model of heart failure induced by isoproterenol . It forms a retinal pigment in human eyes, and high dietary intake of lutein is positively correlated with reduced risk of age-related macular degeneration and cataracts in humans.Characteristics
While it is one of the most widespread naturally occurring carotenoid alcohols, it does not possess any vitamin A activity. Xanthophyll is a yellow pigment, which can be isolated from certain natural products, and produced synthetically.Xanthophyll is the major substance causing yolks to have a deeper yellow color. It has no nutritive value. Years ago when chickens ran freely on the farm they ate grass which contains xanthophyll. Modern production units put enough xanthophyll in the ration of chickens to produce a medium-yellow yolk.
Feeds that contain large amounts of xanthophylls produce a deep yellow color in the beak, skin, and shank of yellowskinned breeds of chickens. The consumer associates this pigmentation with quality and, in many cases, is willing to pay a premium price for a bird of this type. Also, processors of egg yolks are frequently interested in producing dark-colored yolks to maximize coloration of egg noodles and other food products. The latter can be accomplished by adding about 60 mg of xanthophyll per kilogram of diet. In recognition of these consumer preferences, many producers add ingredients that contain xanthophylls to poultry rations.
용도
Xanthophyll is one of the most widespread carotenoid alcohols in nature. Originally isolated from egg yolk, also isolated by chromatography from nettles, algae, and petals of many yellow flowers.일반 설명
Lutein is a yellow dihydroxylated carotenoid which is found to be a common constituent in many dietary supplements.농업용
Xanthophyll is the yellow pigment in leaves containing oxygen and is derived from carotens, which is sometimes absorbed by insects. It is present, for instance, in the skin of caterpillar of cabbage and of white butterfly and in the cocoons of silkworms.크산토필 준비 용품 및 원자재
